What is the cause of blood pools on the placenta?

Patient's question:

No

Doctor's answer:

Hello, according to your description, your ultrasound shows a blood pool at the lower edge of the placenta, which may indicate signs of placental abruption. It is recommended that you pay attention to follow-up checks in the short term. If the blood pool does not enlarge further, there is no need to worry. If the blood pool expands, you will need to be hospitalized.
